Question

Part B : 21= - 4p-11​

Answer 1

p=-8

Explanation:

21=-4p-11

1) Add 11 to both sides:

32=-4p

2) Divide both sides by -4 to isolate p:

p=-8

Answer 2

Answer: p=8

Explanation:

4p-11=21

We move all terms to the left:

4p-11-(21)=0

We add all the numbers together, and all the variables

4p-32=0

We move all terms containing p to the left, all other terms to the right

4p=32

p=32/4

p=8
